A breakthrough this week in nuclear fusion could point the way to a future of carbon-free power. In a press conference Tuesday in California, the Department of Energy revealed that at 1:03 a.m. Dec. 5 ...

Scientists have reviewed chemists' work on "singlet fission," a process in which a single photon generates a pair of excited states. This conversion process has the potential to boost solar cell ...

The process of nuclear fission was first discovered in 1938; however, it wasn’t fully explained until a year later. Today – less than 100 years after its initial discovery – it is the poster child of ...

The discovery of nuclear fission in the 1930s brought with it first the threat of nuclear annihilation by nuclear weapons in the 1940s, followed by the promise of clean, plentiful power in the 1950s ...

The worldwide demand for energy continues to grow at an unprecedented rate. This, combined with the dwindling supply and increasing cost of fossil fuels plus the realization of the threat they pose to ...

Although nuclear power doesn't produce greenhouse gases when generating electricity, the logistical lifecycle of nuclear ...

Bill Gates is looking for an energy miracle. Clean energy may still be in its early stages, but Gates sees a lot of different paths to getting us there other than with solar and wind energy. One ...
